The zone codes required for mobile phone toll payment are paintedon the sidewalks by the Hegyvidék Government to help motorists park. In the first instance, codes were placed for the neighborhoods of medical institutions, public offices, larger commercial units, as well as places further away from parking machines. It is worth knowing that as a result of the transformation of the parking system in the capital, the rules have also changed in the Hegyvidék, not only have parking fees increased, but the fee payment period has also been extended to 22 and 20 hours, respectively. Instead of the previous, multiple mobile codes, only two are now in effect in District XII: 3123 in Zone A and 3121 in Zone B.
